Air Miles Tower Trimming Down and Smartening Up for LEED EB:O+M When the Air Miles Tower was built in 1991, it boasted a then-state-of-the-art digital building automation system and innovative design strategies to save energy and streamline building operation. As time passed, however, the equipment aged and efficiency took a back seat to more simplified operating practices.  In 2010, Dundee REIT, which acquired the property just two years earlier, began planning to upgrade the building’s aging equipment and recognized an opportunity to once again make the building an industry leader in operation and maintenance.  Encouraged by “eco-conscious” anchor tenant LoyaltyOne [operator of the AIR MILES Reward program], Dundee began the process to achieve LEED Canada EB:O+M Gold certification.

Owner and tenants pitch in Dundee realized that in order to reduce the building’s impact on the environment, it would need to make changes to the way that it operates the building and the materials that are used in its operations.  This would go far beyond simply having a recycling program. Moving beyond their already progressive waste diversion program which included not only the traditional paper, cardboard bottles and cans but also organics, toners, e-waste and batteries, they introduced a number of  standards for procurement. The framework began with an overarching

sustainable purchasing policy which outlined the overall environmental goals for the building, including items like percentage of recycled content, a preference for local suppliers, and healthy building materials like FSCcertified wood and low-VOC products.    The responsibilities to carry out these policies were shared by Dundee and their tenants, who adjusted their activities to incorporate the more stringent environmental guidelines for their own suite renovations. Today, the benefits are shared by all; the tenants have healthier work spaces, the operators have better tools with which to manage the building, and the owner is seeing significant energy savings that will offset the majority of the capital upgrade costs. But the most impressive part of the project is that all of these upgrades took place while the building was occupied, barely missing a beat.

Inspiring the Future The Hospital for Sick Children

The Hospital for Sick Children [SickKids] is recognized as one of the world’s foremost paediatric health care institutions and is Canada’s leading centre dedicated to advancing children’s health through the integration of patient care, research and education. Currently, SickKids’ 2,000 research staff are scattered in buildings throughout Toronto’s downtown Discovery District, but this fall, they will be moving into their new building, the Peter Gilgan Centre for Research and Learning. The Gilgan Centre is a LEED Gold targeted, 750,000 sq ft, 21-storey tower located on the northwest corner of Bay and Elm streets.

Sustainability is a key driver for SickKids and the Gilgan Centre is no exception. To gain a better understanding of how sustainability objectives were established and eventually realized at this impressive new facility, the Greater Toronto Chapter spoke to Wayne Walker of SickKids, Mike Szabo of Diamond Schmitt Architects and Mike Williams of CDML who are the project’s owner, architect and sustainability consultant, respectively.

development of our new facility to be undertaken in an environmentally responsible manner. The Gilgan Centre is aiming to achieve LEED Gold certification and will set the standard for energy efficiency and sustainable infrastructure in Toronto’s Discovery District. The development of a world class, green building not only allows us to attract and retain the best and brightest scientists and researchers from the around the world but will also contribute to the health of our environment for the generations of children and families to come.

Q: Wayne Walker, what features of a green building make it an attractive place to work? 2

By setting a green agenda, we were committed to providing an indoor environment that is both productive and engaging. In both design and construction of the new research and learning facility, we focused on features such as daylight, views to the outdoors, the selection of healthy materials and waste management, to name a few.

Set in Toronto’s emerging Junction Triangle neighbourhood, Union Lofts is a unique 43-unit urban infill project being built by Windmill Developments. The project consists of two parts; the adaptive reuse of the red brick Neo-Gothic church at the northeast corner of Perth and Wallace Avenue, and a new concrete and steel frame “Vestry” building being built on the site of the current church parking lot.

Windmill Developments has achieved LEED Platinum status on all of its past residential projects and hopes to achieve the same for Union Lofts. Successfully meeting this goal will make Union Lofts part of an elite group of projects since it will become the first multiresidential condominium in Toronto to be awarded Platinum status.

Vestry [left] and Church [right] from Perth Avenue [1]. The project’s massing is carefully scaled to fit with the surrounding neighbourhood [2].


Sustainability principles were carefully incorporated into all aspects of the project’s planning and design. The adaptive reuse of the historic church ensures that the embodied energy of the building’s original construction will not be lost. Preserving the

‘green’—situated within short walking distance of both Lansdowne and Dundas West subway stations, multiple bus routes, and the soon to be completed Union-Pearson Express GO line, residents of Union Lofts will have convenient access to a multitude of alternative transit options. The interior spaces within the development will be equipped with high quality finishes and capitalize on energy efficient heating and cooling technologies. Each unit will be ventilated with its own Energy Recovery Ventilator to bring fresh outdoor air into the unit while using energy drawn from outgoing air to heat or cool it accordingly. The core of the development’s HVAC system will be a hybrid geo-exchange central plant, consisting of 14 bore holes drilled beneath the Vestry and a small boiler to

supplement heating on the coldest days of the year. This system will significantly reduce the project’s carbon emissions and will future-proof residents from rising energy prices. Other notable sustainability features include a stormwater infiltration system that captures 100% of stormwater on-site; submeters for electricity, water, and thermal energy; FSC certified engineered hardwood flooring in the suites; low-VOC paints and cabinetry; very high efficiency plumbing and lighting fixtures as well as appliances; exterior bricks for the Vestry made from recycled fly ash; native plants and drought resistant landscaping; double glazed, argon filled windows with low e- coating; individual heat pumps with programmable thermostats; and secure resident and visitor bicycle parking. Using healthy, green interior finishes will ensure that Union Lofts is a place that purchasers feel good about coming home to.

While modern state-of-the-art technologies are breathing new life into the historic building, many of the original interior features are being salvaged. Martin Scott of Forever Interiors owns and operates a salvage furniture store near Dundas and Keele. Over the past few months, he has been busy crafting a variety of original benches, signs, and blackboards [PewBoards] from the numerous oak church pews salvaged from Union. The building also housed an 849 pipe Casavant Frères pipe organ built in 1924. After considerable effort to find a suitable new home for the instrument, the developer is donating it to the Cathedral of the Transfiguration in Markham. Union Lofts is a great success story of respecting our past while looking forward into the future.

Kingston Park Pavilion Showcasing Salvaged Local Wood With over 10 million trees in Toronto alone, GTA residents are fortunate to live in a thriving and mature urban forest that cleans our air, beautifies our streets and provides countless ecological and social benefits. While the urban forest is not threatened by fire or large-scale logging, it is currently being attacked by invasive species similar to the Mountain Pine Beetle, which recently devastated the forests of the Rocky Mountains in British Columbia.

A native to Asia and Eastern Russia, the Emerald Ash Borer [EAB] was discovered in North America in 2002 and in Toronto in 2007. Attacking the bark and feeding systems of healthy Green and White Ash trees, the EAB has already killed an estimated 50 to 100 million trees in North America, and is expected to kill nearly all of the 860,000 Ash trees which line Toronto’s streets, parks and backyards by 2020. This die off will have a significant impact on the urban ecosystem in the GTA, yet it provides an opportunity to incorporate local heritage into our buildings. Ash is a very strong hardwood, ideal for use in furniture but tougher to work with as a building material than cedar, for example. However, this toughness means it is durable to both human and natural impacts and is excellent for use as siding, flooring, soffit, facia and much more. [Continues p.24]

The design mimics the corn cribs found throughout the ChathamKent landscape, giving the park a stronger visual connection to the community [4]. Chatham-Kent was one of the first municipalities hit by the EAB in Ontario, and in partnership with architecture firm Brown and Storey they incorporated salvaged local ash into the redesign of the Kingston Park Pavilion, which won a Wood Works award for excellence in wood building in 2011. Salvaged ash was central to the key objective of the new Pavilion, which architect Kim Storey described as “to turn around the standard utilitarian image of the ‘concrete block field houses’ that seem to proliferate through city parks”. Since the redesign, Kingston Park is now the most popular park in Chatham-Kent with over 1,000 visitors daily in a city of 30,000. Deborah Veccia of the Chatham-Kent Parks Department credits the ash with giving the Pavilion a much softer design and feel than you would typically have in a municipal park. As well, the wood and design were intended to mimic the corn cribs found throughout the Chatham-Kent landscape and have given the park a stronger visual connection to its community and surroundings. “The loss of the ash trees in Southwestern Ontario was tragic” says Storey, and in Kingston Park instead of going to Ontario’s strained landfills, this innovative approach gave the ash “a second life”. In addition, the new park pathways use recycled concrete paving slabs from old pool decks demolished in the park, upon which you can still see the yellow ‘No Running’ warnings. Storey says this also memorializes the “thousands of children’s feet ‘not running’ across the pool deck and now running across Kingston Park”. The on-going devastation of the GTA’s Ash trees is tragic yet through salvaging and re-use, this part of our natural heritage can be saved and incorporated into buildings throughout the region to give us a stronger sense of place, to prevent our forests from going to landfill, and to bring us closer to our trees upon which we depend for a healthy and green urban environment.

From Gold to Platinum The Earth Rangers Centre [ERC] opened its doors in 2004. Designed to be office space, an animal rehabilitation hospital and long-term animal care facility, this unique building was designed to publicly affirm the environmental mission of its owner, Earth Rangers. Having achieved LEED NC Gold certification, management set the task of reaching LEED Platinum certification for Existing Buildings, Operations and Maintenance [EB:O+M].

The first step was an energy and water audit, whose goal was to provide a realistic blueprint for achieving carbon footprint reductions and energy neutrality, while exploring revenue-generating opportunities [such as Ontario’s Feed-in-Tariff program]. The resulting energy and water management plan included metrics such as cost, energy savings, priorities for ease of implementation, and expected before operational operational impacts expected. Next came the installation of an 80-point energy metering and monitoring system, along with seven water meters, and nine thermal energy meters. The system provides real-time data through a web interface, and contributed to LEED EB credits that were not attainable otherwise. In general, the plan to get to net-zero energy, carbon neutral-

Energy efficiency means little to tenants if the space is not comfortable. Many different strategies had been tried to reduce energy consumption, including adjusting the heating and cooling set points, and providing sweaters for staff. This was met with considerable occupant resistance and was soon abandoned. However, more orthodox commissioning procedures and improvements in automation control meant that proper thermal conditions could be maintained, regardless of season - and thanks to the ground source system - efficiently so. These improvements were documented for the LEED EB:O+M certification process. A 100% renewable energy contract to purchase EcoLogo-certified, low-impact hydroelectric and wind grid power

The installation of low-flow aerators and low-consumption fixtures meant that the solar thermal preheat was not working as designed. This was identified during commissioning, and resulted in a plumbing and automation sequence change to realize the benefits of the solar thermal system. Energy metering is currently being used to verify the modelled 20,000 kWh per year in energy savings. Once commissioned, these capital improvements resulted in dramatic energy consumption reductions. Two full years of data show that 90% of natural gas use has been displaced, and the carbon footprint of the building has dropped 40%. 2011 energy consumption was 17% below 2010 levels, contributing to 12 of 18 possible LEED EB energy-related points.

As temperatures fall in winter, heating costs inevitably rise. In response, Canadians pull out their slippers, light the hearth and vigilantly monitor their thermostats, but what more can be done? According to collaborative research led by Ryerson University, a simple change in the way we live in our homes, and the introduction of a heat pump, could save up to 80% on energy consumption. Russell Richman, a professor in the Department of Architectural Science at Ryerson University, is the co-principal investigator of an on-going research project that explores the practicality of Nested Thermal Envelope Design, a home construction design that employs zonal heating.

House inside a house concept could mean huge energy savings The nested thermal envelope design has two key components. First, the home must be divided into two different zones; the perimeter and the core. The core is the home’s main living area, for example, the kitchen, the living room and bedrooms. The perimeter is those less often used rooms, such as a formal dining room, sunrooms and secondary bathrooms. Secondly, the home must have a small heating unit that cycles heat from the perimeter into the core during the winter season. The heat pump funnels heat lost to the perimeter back into the core of the home, before it escapes the perimeter and is lost to the exterior of the home. To take full advantage of the design, the home’s core must be set at a reasonable temperature, for example 21°, while the perimeter stays at 5°. It is important to note that living in the core of the home is only necessary during the colder months, when the desire to save money on heating costs is at its height and when the disparity between indoor and outdoor temperatures is greatest. After drafting the original design, the research team tested it using a building energy simulation program, called EnergyPlus. Calculations revealed up to 80% in energy savings. Over the past winter, the researchers moved into the next stage of the project. The nested thermal envelope design was implemented into a home in downtown Toronto. The team elected test subjects to live in the home, beginning with a student and, later on, the home will become a residence for visiting professors. The research team will track behaviour patterns and get feedback from the occupants themselves.

“The question is, is it worth the additional effort of installing a heat pump? The pump needs to be servicing a lot of energy in order to validate this design,” says Richman. “There are so many research questions to be answered with the house. It’s always exciting to take theoretical research and turn it into practice.” Richman and his colleagues hope to collect data from the home and its inhabitants over the next five years, after which time they will continue their research with a custom built home. The group’s preliminary findings were published in the November 2012 issue of Energy and Buildings.
